Definitions
- This invention relates to changing elevator service calls in response to messages transmitted by electromagnetic radiation between the elevator system and a portable device borne by a user.
- Elevator systems have recently been provided with two features which are thought to save considerable passenger time and increase the carrying capacity of a given elevator installation.
- the first of these is utilizing destination calls, by which the passenger does not simply call an elevator to his floor, but at the same time informs the elevator of the intended destination floor.
- This allows the dispatcher (typically a suitably programmed computer) to allocate the call to the most appropriate car, taking into account not only the origin, but also the destination of the passenger.
- a second feature causes passengers to enter their calls while still at some distance (equivalent to about ten seconds, in one case) from the elevator, whereby the dispatcher can attempt to cause the elevator to arrive at nearly the same time that the passenger reaches the elevator.
- the advance calls are entered by destination call buttons disposed remotely from the elevator in the passageways leading to the elevator.
- the calls are entered either automatically by, or in response to pressing keys on, personal radio transmitters which transmit an identification (ID) number utilized to automatically enter a prearranged destination call or a key-selected call.
- ID identification
- Typical problems with these systems include numerous false calls. Some of the false calls are caused by human error, particularly when ten-key entry panels are utilized, which is common in buildings having more than ten or twenty floors. Other false calls are registered as a consequence of pranks or vandalism. Still other false calls are caused by the person desiring to go to a destination other than his passively-entered, prearranged destination, deciding not to enter the elevator yet (such as to purchase a newspaper on the way in) or simply changing his mind. Such systems have not had any adequate way to change calls, since there is a need to associate pressing of buttons on a destination call device with the ID number of a badge, the two of which are normally mutually exclusive ways of making calls.
- Objects of the invention include improved remote entry of elevator calls; improved automatic entry of elevator calls; improved revision of elevator calls; improved revision of elevator calls, including automatically entered elevator calls; reducing false calls in an elevator system responding to destination calls; reducing the response to false calls in an elevator system employing automatic destination calls; providing improvements in elevator system operation; and reduced elevator service time.
- an elevator system comprising a plurality of elevators each having a car moveable within a related hoistway for transporting passengers vertically between floors of a building, a controller for receiving service messages initiated by passengers requesting elevator service from an origin floor to a destination floor, for providing hall call commands to said elevators to cause a selected elevator to provide service in response to related ones of said call messages, and for providing car call commands to said elevators to cause each said selected elevator to stop at a corresponding destination floor, a receiver for receiving electromagnetic messages transmitted in proximity therewith and for providing said messages to said controller, and a plurality of remote control devices to be borne and used by a passenger in requesting elevator service, said remote control device having a transmitter for transmitting electromagnetic call messages to said receiver for transfer to said controller, each call message transmitted by said device including a component identifying the particular device that transmitted the message, characterized by said remote control device having passenger activated means for initiating transmission of a call cancellation message.
- a method of correcting calls for service in a multi-elevator system having a controller for allocating calls to selected elevators comprising providing at each access floor a receiver for receiving electromagnetic messages transmitted in proximity therewith and for providing said messages to said controller; providing passengers with remote control devices for requesting elevator service, said remote control devices having a transmitter for transmitting electromagnetic messages to said receiver for transfer to said controller, each message transmitted by said device including a component identifying the particular device that transmitted the message, and having passenger activated means for initiating transmission of a call cancellation message and for initiating transmission of a call message which includes a component identifying a destination floor designated by said passenger activated means, initiating transmission of a call message from one of said devices for a first destination floor, initiating transmission of a call cancellation message from said one of said devices, cancelling any car stop for a call request by said one of said devices and requested by any other device, and initiating a call message from said one of said devices for a second destination floor.
- a method of correcting calls for service in a multi-elevator system having a controller for allocating calls to selected elevators comprising providing at each access floor a receiver for receiving electromagnetic messages transmitted in proximity therewith and for providing said messages to said controller, and providing passengers with remote control devices for requesting elevator service, said remote control devices having a transmitter for transmitting electromagnetic call messages to said receiver for transfer to said controller, each call message transmitted by said device including a component identifying the particular device that transmitted the message, characterized by the improvement comprising said remote control devices having passenger activated means for initiating transmission of a call cancellation message which includes a component identifying a destination floor designated by said passenger activated means, assigning a call requested by each said call message to one of said elevators, sending an identifying message from each device upon such device entering one of said elevators, said identifying message including said device identifying component, and in the event that the identifying component of one such device entering one elevator is the same as the identifying component of a particular call assigned to another of said elevator

- Each of the corridors 26-28 has corresponding prompt beacons 32-37 that periodically (several times per second) transmit a prompt to alert devices of the invention (not shown in Fig. 1) that the general proximity of the elevators has been reached.
- the prompt is electromagnetic radiation, which may be selected from various available bands, such as 125 KHz or 315 MHz.
- Each of the elevator landings 23-25 has an electromagnetic transceiver 39-41 which can both transmit and receive messages by means of electromagnetic radiation.
- each person 43-45 is shown entering corresponding corridors 26-28 at a time when each prompt transmitter 35-37 is transmitting an electromagnetic signal which comprises a beacon type prompt.
- Each person 43-45 is bearing a verbal remote control device not shown in Figs. 1-8 for clarity.
- each verbal remote control device will issue an audible prompt, such as a beep (Fig. 1), for the person bearing the device to hear.
- the audible prompt as is shown in Fig. 2, the persons 43 and 44 desirous of entering an elevator will respond verbally.
- the person 44 On the fourth floor, the person 44 simply says "elevator", which causes the verbal remote control device borne by him to transmit, electromagnetically, a message which includes information such as "elevator requested", the identification number of the device (either k or j in the example of Fig. 2), and whether or not the bearer has indicated a desire to go to a floor other than the floor that the bearer normally goes to, referred to as the default floor herein.
- the person 43 has requested the elevator to take him to the ninth floor, whereas the person 44 has requested the elevator, and decides to go to his default floor.
- the person 45 has said nothing, thereby indicating that he is not heading for the elevator.
- the verbal remote control devices borne by the persons 43-45 might have synthesized the question “Elevator?", instead of using "beep” as a prompt.
- the person 43 could have replied “yes...9” or simply “9", and the person 44 could have simply replied “yes”.
- the person 45 might either remain silent or answer with the word "no".
- the persons might use functional words to enter a specific call, such as "gym", "office” or "cafeteria”.
- any human-discernable prompt such as vibration (as in conventional paging units) may be used instead of audible prompts.
- the verbal remote control device on each person When the verbal remote control device on each person has received a verbal reply, it will transmit a corresponding message to a landing transceiver 39, 40, 41 (or a receiver positioned in any other suitable way), which includes the ID number of the device (person) and any request for a destination floor different from the default floor.
- a landing transceiver 39, 40, 41 or a receiver positioned in any other suitable way
- the device on person 45 does not transmit any response, in this example.
- the dispatcher of the elevator system which may be any conventional dispatcher, enters a hall call for the corresponding floor (that is, floor 3 for person 43 and floor 4 for person 44), and also enters a destination request for the indicated floor (floor 9 for person 43) or the default floor if no request were made (for instance, floor 14 for person 44).
- the destination request is used in the dispatcher for making call allocations, but is not entered as a car call until the car stops at the origin floor, or optionally, until the related passenger enters the cab.
- the dispatcher selects which of the elevators (car 1-car 4) is the most appropriate to respond to the combined hall call/car call.
- each transceiver 39, 40 electromagnetically transmits a corresponding message which identifies the ID of the device entering the call request, as shown in Fig. 3.
- the transceiver 39 transmits a message including the information: the ID of the device requesting the call is k, and the call has been assigned to car four.
- the transceiver 40 transmits a message including that the ID is j, and the call has been assigned to car 3.
- the verbal remote control device of the present invention utilizes voice synthesis to announce the car assignment for the call through a loudspeaker to the bearer thereof as shown in Fig.
- the hall calls are all entered in cars for the pick up floors, the destination floors are noted, and the dispatcher knows the identification number of the persons (devices) who have requested those calls.
- the verbal remote control device will be in range of a corresponding prompt beacon 32-34.
- the verbal remote control device borne by him would transmit a message cancelling the hall call and destination call assigned to car 4 requested on floor 3 for the person whose device ID number is k.
- the person 43 could have said "19" or "office” to change the call.
- An important aspect of the invention is that service call messages by a unique device allows matching each new request with a specific previous request which must be concomitantly changed, according to this invention.
- a transceiver 50 within the cab 52 of elevator 3 is directional, as indicated by the dotted lines 53. This is to prevent the transceiver 50 from recognizing the transmissions from the verbal remote control device on the person 44, prior to the person 44 entering the cab 52, as illustrated in Fig. 6. Once the transceiver 50 receives transmissions from the verbal remote control device borne by the person 44, it is known that the person is within the cab 52.
- the verbal remote control borne by the person 54 will respond to a prompt from the beacon 48 to inform the transceiver 50 of that fact by means of an electromagnetically transmitted message including that the ID equals m.
- the ID number allows the dispatcher to cancel a car stop for this call within another car unless that call was also requested by another ID number; and the destination request may either be cancelled or retained. Either way, the dispatcher can inquire of the person's intentions, if desired.
- the dispatcher will cause the transceiver 50 to send an electromagnetic message to the verbal remote control device being borne by the person 54 having the ID number m, requesting which floor is desired by that person, as shown in Fig. 8.
- the verbal remote control device borne by the person 54 will, by speech synthesis, express the command "floor please".
- the specific person can have the question addressed to her by her own verbal remote control device, rather than having a loudspeaker within the cab address the question to all of the passengers.
- the actual voice synthesis can have a very wide variety of sounds - high pitch, low pitch, young, old, male, female, and so forth - so that persons generally will be able to distinguish the voice synthesized words of their devices from those of other voice synthesizers in the vicinity.
- a verbal remote control device 60 may include either a voice recognition function 62 which is connected to an acoustoelectric transducer such as a microphone 63 with which it can receive the words 64 of a person, such as the person 44, or it may include a voice synthesizer 69 which feeds an electroacoustic transducer such as a loudspeaker 70 so as to issue verbal information 71 to a person such as the person 44, or it may include both the apparatus 62, 63 and the apparatus 69, 70.

- the recognition 62 and the synthesis 69 will have appropriate connections 74, 75 to a microprocessor 76 which in turn has connections 77 to a transceiver 78.
- the transceiver 78 is connected to an antenna 79.
- the electromagnetic radiation used for message transmission is preferably at radio frequencies, rather than optical or near optical frequencies since it will pass through clothing easily and is not as easily blocked by other persons or objects. All of this is conventional, well within the skill of the art, and forms no part of the present invention.
- an elevator system 82 with which the verbal remote control devices of the present invention may communicate includes at least one hall beacon for each hall (perhaps several per floor), such as the hall beacon 36 on the fourth floor corridor 27, a transceiver and a landing beacon for each landing, such as the transceiver 40 and beacon 33 for the fourth floor landing 24, and a car transceiver and beacon for each elevator car, such as the transceiver 50 and the beacon 48 on car 3.
- the present invention is designed to eliminate the need for conventional hall fixtures, such as fixtures 83 for the fourth floor landing 24, and is designed to eliminate the need for car call buttons provided on a car operating panel (COP), such as the COP 84 for car 3.
- COP car operating panel
- the fixtures 83 and COPs 84 may be provided in any utilization of the present invention, if desired.

Abstract
Description
- This invention relates to changing elevator service calls in response to messages transmitted by electromagnetic radiation between the elevator system and a portable device borne by a user.
- Elevator systems have recently been provided with two features which are thought to save considerable passenger time and increase the carrying capacity of a given elevator installation. The first of these is utilizing destination calls, by which the passenger does not simply call an elevator to his floor, but at the same time informs the elevator of the intended destination floor. This allows the dispatcher (typically a suitably programmed computer) to allocate the call to the most appropriate car, taking into account not only the origin, but also the destination of the passenger.
- A second feature causes passengers to enter their calls while still at some distance (equivalent to about ten seconds, in one case) from the elevator, whereby the dispatcher can attempt to cause the elevator to arrive at nearly the same time that the passenger reaches the elevator. In one case, the advance calls are entered by destination call buttons disposed remotely from the elevator in the passageways leading to the elevator. In other cases, the calls are entered either automatically by, or in response to pressing keys on, personal radio transmitters which transmit an identification (ID) number utilized to automatically enter a prearranged destination call or a key-selected call.
- Typical problems with these systems include numerous false calls. Some of the false calls are caused by human error, particularly when ten-key entry panels are utilized, which is common in buildings having more than ten or twenty floors. Other false calls are registered as a consequence of pranks or vandalism. Still other false calls are caused by the person desiring to go to a destination other than his passively-entered, prearranged destination, deciding not to enter the elevator yet (such as to purchase a newspaper on the way in) or simply changing his mind. Such systems have not had any adequate way to change calls, since there is a need to associate pressing of buttons on a destination call device with the ID number of a badge, the two of which are normally mutually exclusive ways of making calls. The use of destination call buttons, particularly in the landing during the morning rush, has been found to cause great delay in moving passengers onto the elevators, since typically lines are formed at each call entry panel. Because of the confusion and delay, passengers enter cars without having registered a call. In elevator systems utilizing destination hall calls, there typically is no car operating panel within each car, thereby providing no way to enter a car call once the passenger is in the car. Even if a car call could be entered in the elevator, the system would not know what previous destination call should be cancelled, since there is no way to associate the two. If one person simply cancelled a hall call or a destination call to some floor, other passengers wishing that service would lose it. If a passenger decides not to board or not to exit, the unnecessary floor stop unduly delays other passengers.
- Objects of the invention include improved remote entry of elevator calls; improved automatic entry of elevator calls; improved revision of elevator calls; improved revision of elevator calls, including automatically entered elevator calls; reducing false calls in an elevator system responding to destination calls; reducing the response to false calls in an elevator system employing automatic destination calls; providing improvements in elevator system operation; and reduced elevator service time.
- In accordance with one aspect of the present invention, there is provided an elevator system, comprising a plurality of elevators each having a car moveable within a related hoistway for transporting passengers vertically between floors of a building, a controller for receiving service messages initiated by passengers requesting elevator service from an origin floor to a destination floor, for providing hall call commands to said elevators to cause a selected elevator to provide service in response to related ones of said call messages, and for providing car call commands to said elevators to cause each said selected elevator to stop at a corresponding destination floor, a receiver for receiving electromagnetic messages transmitted in proximity therewith and for providing said messages to said controller, and a plurality of remote control devices to be borne and used by a passenger in requesting elevator service, said remote control device having a transmitter for transmitting electromagnetic call messages to said receiver for transfer to said controller, each call message transmitted by said device including a component identifying the particular device that transmitted the message, characterized by said remote control device having passenger activated means for initiating transmission of a call cancellation message.
- In accordance with a second aspect, there is provided a method of correcting calls for service in a multi-elevator system having a controller for allocating calls to selected elevators, comprising providing at each access floor a receiver for receiving electromagnetic messages transmitted in proximity therewith and for providing said messages to said controller; providing passengers with remote control devices for requesting elevator service, said remote control devices having a transmitter for transmitting electromagnetic messages to said receiver for transfer to said controller, each message transmitted by said device including a component identifying the particular device that transmitted the message, and having passenger activated means for initiating transmission of a call cancellation message and for initiating transmission of a call message which includes a component identifying a destination floor designated by said passenger activated means, initiating transmission of a call message from one of said devices for a first destination floor, initiating transmission of a call cancellation message from said one of said devices, cancelling any car stop for a call request by said one of said devices and requested by any other device, and initiating a call message from said one of said devices for a second destination floor.
- In accordance with a third aspect, there is provided a method of correcting calls for service in a multi-elevator system having a controller for allocating calls to selected elevators, comprising providing at each access floor a receiver for receiving electromagnetic messages transmitted in proximity therewith and for providing said messages to said controller, and providing passengers with remote control devices for requesting elevator service, said remote control devices having a transmitter for transmitting electromagnetic call messages to said receiver for transfer to said controller, each call message transmitted by said device including a component identifying the particular device that transmitted the message, characterized by the improvement comprising said remote control devices having passenger activated means for initiating transmission of a call cancellation message which includes a component identifying a destination floor designated by said passenger activated means, assigning a call requested by each said call message to one of said elevators, sending an identifying message from each device upon such device entering one of said elevators, said identifying message including said device identifying component, and in the event that the identifying component of one such device entering one elevator is the same as the identifying component of a particular call assigned to another of said elevators, cancelling said particular call in said another of said elevators unless also requested by another one of said devices.
- In accordance with a fourth aspect, there is provided a method of correcting calls for service in a multi-elevator system having a controller for allocating calls to selected elevators, comprising providing at each access floor a receiver for receiving electromagnetic messages transmitted in proximity therewith and for providing said messages to said controller, providing passengers with remote control devices for requesting elevator service, said remote control having a transmitter for transmitting electromagnetic messages to said receiver for transfer to said controller, each message transmitted by said device including a component identifying the particular device that transmitted the message and having passenger activated means for initiating transmission of a call cancellation message and for initiating transmission of a call message which includes a component identifying a destination floor designated by said passenger activated means, initiating transmission of a call message from one of said devices for a first destination floor, assigning a call requested by each said call message to one of said elevators, sending an identifying message from each device upon such device entering one of said elevators, said identifying message including said device identifying component, in the event that the identifying component of one such device entering one elevator is the same as the identifying component of a particular call assigned to another of said elevators, cancelling a stop car for said particular call in said another of said elevators unless said stop is also for a call requested by another one of said devices, otherwise initiating transmission of a call cancellation message from said one of said devices, and cancelling any car stop for a call requested by said one of said devices and not requested by any other device, and initiating a call message from said one of said devices for a second destination floor.
- The present invention may be practiced with a personal remote control device which communicates verbally with the user or with a device which uses switches, displays and/or other means of communicating with the user.
- The invention allows individual users to cancel previously requested calls, to change automatically entered calls, to change calls previously entered by the passenger, without subjecting the elevators to false stops, and without cancelling of stops related to other passengers' requests for service. The invention thereby permits use of destination call registration, without all of the wasteful, false call difficulties attendant destination call elevator systems known to the prior art.

- Referring now to Fig. 1, three floors of a building 20-22, each include an elevator landing 23-25, corresponding entrance corridors 26-28, and other corridors 29-31. Each of the corridors 26-28 has corresponding prompt beacons 32-37 that periodically (several times per second) transmit a prompt to alert devices of the invention (not shown in Fig. 1) that the general proximity of the elevators has been reached. The prompt is electromagnetic radiation, which may be selected from various available bands, such as 125 KHz or 315 MHz. Each of the elevator landings 23-25 has an electromagnetic transceiver 39-41 which can both transmit and receive messages by means of electromagnetic radiation. In Fig. 1, three persons 43-45 are shown entering corresponding corridors 26-28 at a time when each prompt transmitter 35-37 is transmitting an electromagnetic signal which comprises a beacon type prompt. Each person 43-45 is bearing a verbal remote control device not shown in Figs. 1-8 for clarity. In response to the beacon prompt, each verbal remote control device will issue an audible prompt, such as a beep (Fig. 1), for the person bearing the device to hear. In response to the audible prompt, as is shown in Fig. 2, the
persons 43 and 44 desirous of entering an elevator will respond verbally. On the fourth floor, theperson 44 simply says "elevator", which causes the verbal remote control device borne by him to transmit, electromagnetically, a message which includes information such as "elevator requested", the identification number of the device (either k or j in the example of Fig. 2), and whether or not the bearer has indicated a desire to go to a floor other than the floor that the bearer normally goes to, referred to as the default floor herein. As seen in Fig. 2, it is assumed that the person 43 has requested the elevator to take him to the ninth floor, whereas theperson 44 has requested the elevator, and decides to go to his default floor. In Fig. 2, theperson 45 has said nothing, thereby indicating that he is not heading for the elevator. Alternatively, when prompted by the transceivers 34-36, the verbal remote control devices borne by the persons 43-45 might have synthesized the question "Elevator?", instead of using "beep" as a prompt. In reply to the request, the person 43 could have replied "yes...9" or simply "9", and theperson 44 could have simply replied "yes". In a system so devised, theperson 45 might either remain silent or answer with the word "no". Optionally, the persons might use functional words to enter a specific call, such as "gym", "office" or "cafeteria". If desired, any human-discernable prompt, such as vibration (as in conventional paging units) may be used instead of audible prompts. - When the verbal remote control device on each person has received a verbal reply, it will transmit a corresponding message to a
landing transceiver person 44 transmits a message that simply identifies the bearer as ID = j. The device onperson 45 does not transmit any response, in this example. - Once the
transceivers floor 3 for person 43 andfloor 4 for person 44), and also enters a destination request for the indicated floor (floor 9 for person 43) or the default floor if no request were made (for instance, floor 14 for person 44). The destination request is used in the dispatcher for making call allocations, but is not entered as a car call until the car stops at the origin floor, or optionally, until the related passenger enters the cab. The dispatcher then selects which of the elevators (car 1-car 4) is the most appropriate to respond to the combined hall call/car call. Once the assignment is made, it is communicated to thetransceiver floor 3 andfloor 4, respectively). In turn, eachtransceiver transceiver 39 transmits a message including the information: the ID of the device requesting the call is k, and the call has been assigned to car four. Similarly, thetransceiver 40 transmits a message including that the ID is j, and the call has been assigned tocar 3. In response, the verbal remote control device of the present invention utilizes voice synthesis to announce the car assignment for the call through a loudspeaker to the bearer thereof as shown in Fig. 3. Thus, the verbal remote control device borne by the person 43 announces "car 4", and the verbal remote control device borne by theperson 44 announces "car 3". Of course, no announcement is made to theperson 45 who begins to turn the corner into the additional corridor 31. - At this point in the sequence, the hall calls are all entered in cars for the pick up floors, the destination floors are noted, and the dispatcher knows the identification number of the persons (devices) who have requested those calls. As seen in Fig. 4, by the time an intended passenger reaches a corresponding one of the elevator landings 23-25, the verbal remote control device will be in range of a corresponding prompt beacon 32-34. Before or after reaching the
landing 23, if the person 43 said "cancel", the verbal remote control device borne by him would transmit a message cancelling the hall call and destination call assigned tocar 4 requested onfloor 3 for the person whose device ID number is k. On the other hand, instead of cancelling the call, the person 43 could have said "19" or "office" to change the call. An important aspect of the invention is that service call messages by a unique device allows matching each new request with a specific previous request which must be concomitantly changed, according to this invention. - Referring now to Fig. 5, the
person 44 is standing at thelanding 24 waiting to enterelevator 3, thehoistway doors 46 andelevator doors 47 of which have just opened. Abeacon 48 may cause response from each device in the car. Atransceiver 50 within thecab 52 ofelevator 3 is directional, as indicated by the dottedlines 53. This is to prevent thetransceiver 50 from recognizing the transmissions from the verbal remote control device on theperson 44, prior to theperson 44 entering thecab 52, as illustrated in Fig. 6. Once thetransceiver 50 receives transmissions from the verbal remote control device borne by theperson 44, it is known that the person is within thecab 52. - Referring to Fig. 7, if another person 54 who has been assigned to a different elevator at the fourth floor landing 24, nonetheless enters
car 3, the verbal remote control borne by the person 54 will respond to a prompt from thebeacon 48 to inform thetransceiver 50 of that fact by means of an electromagnetically transmitted message including that the ID equals m. The ID number allows the dispatcher to cancel a car stop for this call within another car unless that call was also requested by another ID number; and the destination request may either be cancelled or retained. Either way, the dispatcher can inquire of the person's intentions, if desired. In such case, the dispatcher will cause thetransceiver 50 to send an electromagnetic message to the verbal remote control device being borne by the person 54 having the ID number m, requesting which floor is desired by that person, as shown in Fig. 8. In response, the verbal remote control device borne by the person 54 will, by speech synthesis, express the command "floor please". Thus, the specific person can have the question addressed to her by her own verbal remote control device, rather than having a loudspeaker within the cab address the question to all of the passengers. As is true in common personal computers, the actual voice synthesis can have a very wide variety of sounds - high pitch, low pitch, young, old, male, female, and so forth - so that persons generally will be able to distinguish the voice synthesized words of their devices from those of other voice synthesizers in the vicinity. (Note that checkout persons can tell when the UPC sensor at their station has sounded, even though an identical sound is used at adjacent UPC stations.) After the verbal request is made of the person 54 by the voice synthesizer of the verbal remote control device borne thereby, the person 54 may state a floor number, which will then be transmitted electromagnetically from the verbal remote control device borne by theperson 53 to thetransducer 50 and thence by wire or other suitable communication modality to the dispatcher, so as to enter a call for the destination floor stated by the person 54. If person 54 does not state any floor information, of if in any embodiment no request is made of the person 54, the dispatcher could react to the previously recorded destination call requested for ID = m. - Referring now to Fig. 9, a verbal
remote control device 60, which may optionally be used in practicing the present invention, may include either avoice recognition function 62 which is connected to an acoustoelectric transducer such as amicrophone 63 with which it can receive thewords 64 of a person, such as theperson 44, or it may include avoice synthesizer 69 which feeds an electroacoustic transducer such as aloudspeaker 70 so as to issueverbal information 71 to a person such as theperson 44, or it may include both theapparatus apparatus recognition 62 and thesynthesis 69 will haveappropriate connections microprocessor 76 which in turn hasconnections 77 to atransceiver 78. Thetransceiver 78 is connected to anantenna 79. The electromagnetic radiation used for message transmission is preferably at radio frequencies, rather than optical or near optical frequencies since it will pass through clothing easily and is not as easily blocked by other persons or objects. All of this is conventional, well within the skill of the art, and forms no part of the present invention. - In Fig. 9, an
elevator system 82 with which the verbal remote control devices of the present invention may communicate includes at least one hall beacon for each hall (perhaps several per floor), such as thehall beacon 36 on thefourth floor corridor 27, a transceiver and a landing beacon for each landing, such as thetransceiver 40 andbeacon 33 for the fourth floor landing 24, and a car transceiver and beacon for each elevator car, such as thetransceiver 50 and thebeacon 48 oncar 3. The present invention is designed to eliminate the need for conventional hall fixtures, such asfixtures 83 for the fourth floor landing 24, and is designed to eliminate the need for car call buttons provided on a car operating panel (COP), such as theCOP 84 forcar 3. However, to permit broadest utilization of the elevator system, including usage by persons not having access to a suitable remote control device, thefixtures 83 andCOPs 84, including car call buttons, may be provided in any utilization of the present invention, if desired. Thetransceivers hall fixtures 83 andcar operating panel 84 havenormal connections 86, 87 to adispatcher 88, which may be wires or other suitable communication modality. Thedispatcher 88 is provided withsuitable connections 90 to other floors, andsuitable connections 91 to other cars. - The
voice recognition function 62 andvoice synthesis function 69 may take any suitable form, such as an RSC-164 voice recognition chip provided by Sensory Inc., Sunnyvale, CA, which includes both voice recognition and synthesis. Themicroprocessor 76 may be any suitable microprocessor, and may preferably be one which can enter into an inactive or sleep mode, and be responsive only to receipt of a beacon prompt command through theantenna 79 and thetransceiver 78 to wake it up and initialize it for enabling thevoice recognition 62 and thevoice synthesis 69. Such a microprocessor may be formulated with a PIC 16C84 for example, or any other suitable microprocessor. Thetransceiver 78 is conventional, regardless of the particular design chosen in any implementation of the present invention. - Instead of a verbal remote control device, the invention may be practiced with a remote control device which uses switches and a display to communicate with the user. In Fig. 10, a
remote control device 100 has a plurality ofswitch buttons 102, which may include a device wake-up button, if needed, a call cancellation button, and buttons to enter elevator service calls, which may be numerical, one per floor or ten-key, or which may have prearranged functional significance, such as office, lobby, gym, etc., or both. The device may have adisplay 104 to issue requests and to inform the user, such as of an assigned car. - The foregoing application, and the details thereof, are by way of example only. The invention may as well be used to control other domestic, commercial and industrial apparatus.
